Acceptance criteria for achieving adequate levels of cathodic protection to a well casing is typically based on applying a predetermined amount of current to the well casing, which can be estimated using electrical circuit simulation of the CP circuit models. The simplest electric circuit model to predict the performance of a CP system include the following passive components:
• Anode bed resistance-to-remote earth
• Well casing resistance-to-remote earth
• Flowline resistance-to-remote earth
• Other U/G metallic structures (e.g., grounding, tubing, piping, among others)
• Back EMF of the well casing, anode bed, flowline, and other U/G metallic structure
• Cable resistances
• DC Voltage power supply
